A NEW TELEPHONE.
interesting Experiments Between
Paris and Brussels.

Paris and Brussels with new APP
paratus known as the "micro-telephone
push button" writes Paris correspon-
dent of The London Times. These ex-
periments, which were made on be-
half of the Two telegraphic administra-
live departments OF France and Bel
GUM, produced very lively impress
zion those present, and believe the
new .nln Aus ~ be the most perfect
YET rroducod.
As its name indicates, il has the
form of an ordinary electric push-but-
ton. When the button has been push
ed in, and has made II sound at the
otLcr extremity, il is taken out, and is
lound TO be attached to long electric
wire. There is thus exposed the tele-
phonic plate. which is extremely sensi-
live, so thai where it is necessary to
speak at short distances il is not nee
essary to come close to the instrument.
For communications in the same
street, or the same house, the operator
places the upper part near himself, and
without changing his position he can
speak with the correspondent at the
opposite extremity. He is not obliged
10 put his ear TO the part which con-
iains the button and brings back the
reply. Thus for short distances those
who make use of this apparatus speak
IN their ordinary tone, without chang
Ing their customary attitudes. They
may sit or walk about, and speak just
Is if those they are addressing were
present. When great distances inter
Fene, rs in the experiments performed
.o-day, in which the speakers and
hearers were separated by two hundred
miles, it is necessary to come nearer
TO the apparatus, but without being
obliged to speak quite close TO it,
But what makes this apparatus the
most successful of telephone instru-
ments is, that it can be made for half
a crown-that is to say, for not more
than the price of an ordinary push-but-
button. Now, as it can be fitted to the
electric wire of the ordinary ringing
apparatus, it follows that it introduces
a complete change in our ordinary
modes of intercourse. AT front doors,
in the interior rooms of houses, every
where in short, where the ordinary
electric buttons are used the tele-
phonic buttons may be introduced. 1t
will by this means be possible to give
Dr. receive instructions, to know who is
knocking at the door, to communicate
in short, by speaking as well rs ringing.
On the advantage of this in everyday
life it is unnecessary to dwell. The

The inventor is DIR. Cornelius Herr,
one day nom mated grand officer of the
Legion oil Honor, next day described rs
an emissary of Germany, and lastly
as the friend, adviser, and and con
ddent of Gen. Boulanger. He is in
reality an electr clan whose inventive
talent has been stimulated by his re-
sidence in America, where there is
a boundless demand for Improvement
in electrical apparatus and in all
mechan cal contrivances. The French
minister OF posts and telegraphs, under
whose auspices the experiments were
carried out to-day, has approved the re-
port nude to h m, and proposes to give
orders for the introduction of the new
apparatus into all the public administra-
tive departments as soon as it comes
into use, for as yet it has only been
an exper ment.
